Air conditioning refrigeration now generally uses water, ammonia, carbon dioxide, R12, R22, R134a, R404, R407C, R410 and R600a refrigerants. After 2009, Gree used R290, Jiabing, Zhongwei Refrigeration Company launched R433b, Furui Refrigeration Company launched ER445 series refrigerants, which are more energy-saving, environmentally friendly and efficient refrigerants, commonly known as hydrocarbon refrigerants, non-toxic, and will not cause any damage to the ozone layer. But because they are all alkanes, they are both flammable and explosive. Fluoride is a non-toxic, harmless, non-irritating, non-flammable, non-explosive, non-flash point, environmentally friendly refrigerant with 0 ODP value and very low GWP value.
